e.g.: I was contributing to FreeBSD because I wanted to contribute to BSD licensed-software, with a hope people from FANG would use it, and maybe hire me later. If FreeBSD made a chance to the license, it'd no longer be FreeBSD. It'd be FreeCommonsClause--different project. I wouldn't like to contribute to this.
As a CEO fo a software company, if I were to go and analyze what this license change means to my business, and probably get uncertain answer, I'd rather fork Redis from before the license change, and run on the copy.
Why? Because the fee for a US software engineer is $X, for a over-sees is $0.3X or $0.5X. Fee for a US copyright lawyer with expertise in software is 10$X. Pay that much money for no value-added to my business makes no sense to me.
